CVE-2024-27878: An app may be able to execute arbitrary code with kernel privileges in Apple macOS
CVE-2024-27878 is a buffer overflow vulnerability in Apple macOS Sonoma that could allow a local application to execute arbitrary code with kernel privileges. The issue was addressed by Apple with improved memory handling and is fixed in macOS Sonoma 14. 6. This vulnerability has a CVSS score of 6. 5, indicating a medium severity level. There are no known exploits in the wild at this time. The vulnerability requires local access with high privileges and user interaction to exploit.
AI Analysis
Technical Summary
CVE-2024-27878 is a buffer overflow vulnerability in the macOS Sonoma kernel that could allow a local application to execute arbitrary code with kernel privileges. The vulnerability was mitigated by Apple through improved memory handling in the macOS Sonoma 14.6 update. The CVSS vector indicates that exploitation requires local access (AV:L), low attack complexity (AC:L), high privileges (PR:H), and user interaction (UI:R), with high impact on confidentiality, integrity, and availability (C:H/I:H/A:H).
Potential Impact
If exploited, this vulnerability could allow a malicious local application to execute arbitrary code at the kernel level, potentially leading to full system compromise including unauthorized access to sensitive data, modification of system files, and disruption of system availability. However, exploitation requires local access with high privileges and user interaction. There are no reports of active exploitation in the wild.
Mitigation Recommendations
Apple has released an official fix for this vulnerability in macOS Sonoma 14.6. Users and administrators should apply this update promptly to remediate the issue. No additional mitigation steps are indicated by the vendor advisory.
